摘要:
The reaction of LLi, (L = [RNC(Me)CHC(Me) = O] (R = C2H4NEt2)), with AlCl3 at -78 degrees C forms the mono-ketiminate product, LAlCl2, 1, while the same reaction at 0 degrees C affords the bis-ketiminate complex, [{(LH)(2)AlCl}(Cl-2)], 2, Reduction of 1 with Li-o, K-o or Mg-o yielded an unusual dimeric aluminum(III) species, [L'AlCl](2), 3, where C-C coupling of the ligand backbone is observed.
